Germany and Britain are piling pressure on other G7 nations to boost the funding they provide for climate action in developing countries this decade, even though Germany did not offer more finance at an international gathering last week.

Ahead of last week's Petersberg Climate Dialogue, climate and development experts and former U.N. chief Ban Ki-moon had urged Germany to commit to doubling its public climate finance by 2025 to an annual €8 billion ($9.6 billion), up from about €4 billion now.

But outgoing German Chancellor Angela Merkel said only that Germany's total climate support — including public and private sources of money — had reached nearly €7.6 billion in 2019.
